form_api conflicks with cck export / import

the form_alter hook rewrites the form adding the devinfo as a fieldset to the form. This causes problems with some other modules like cck's builtin import export.
Solution update form_alter hook to just use drupal_set_message like the node_api function.

This will fix the problem, although I kinda like the DevInfo appearing inside the actual form as it does now.
Maybe just setting the system weight so it runs after everything else would fix this problem.

Either way should work!
